Rear Panel And Audio Connections - Parasound ZoneMaster 2350 Owner's Manual

Rear Panel and Audio Connections

Always disconnect the AC cord to your ZoneMaster 2350 before plugging in or unplugging any
connections. Inserting or removing an interconnect cable's plug while this power amp is turned on can
result in a burst of sound that can damage your loudspeakers. Make sure there is no strain or tension on
any input cables, speaker wires, DC trigger wires or the AC cord that could cause them to pull loose.
Audio Input Connections
Line Input Jacks for Left and Right (Channels 1 and 2)
These are standard line level audio Inputs for each channel. Connect these jacks to the Left and Right
output jacks on your preamp, whole-house audio controller or the zone outputs of your AV receiver.
Speaker Level Input Connector Block for Left and Right (Channels 1 and 2)
The speaker level input enables the ZoneMaster 2350 to connect to any audio receiver or stereo system,
even if it lacks preamp output jacks. This is a high impedance input and the ZoneMaster 2350's Speaker
Level input can connect to the speaker terminals on any receiver or amplifier. This will not reduce the output
power or degrade the sound quality of the speakers that are already connected directly to the "host" receiver
or amplifier. Speaker level audio is internally converted to line level and routed to the Loop Out, Mono Out
and Sub Out jacks. These provide line level outputs to drive additional power amplifier(s) and powered
subwoofers.
Note: You can detach the Speaker Level Input Connector Block from the 2350 to make it easier to
attach and secure the 4 speaker wires. Grip it firmly with your thumb and forefinger to pull it
away from the chassis. It accepts bare wires up to 12AWG (gauge). Each wire should be
twisted tightly and/or tinned with solder to prevent its stray strands from touching the adjacent
wire which will short-circuit the amplifier.
Consistent Polarity Is Important!
You must be careful to maintain polarity between the "host" receiver (or amplifier) speaker terminals and the
Model 2350 speaker Line Level input terminals. Connect the + speaker terminals of the receiver to the +
terminals of the Model 2350's Speaker Level Input connecting block. Connect the – speaker terminals of the
receiver to the – terminals of the Model 2350's Speaker Level Input connecting block. If you do not maintain
correct polarity the Speaker Level Input will not function correctly and there could be no sound.
Note: Connect either the RCA Input jacks or the Speaker Level Input block, but not both.
Note: Using large gauge speaker wire between the receiver and 2350 provides no
performance advantage because the Speaker Level Input consumes only a small
fraction of a watt from your receiver's power output.
